BARRETT GLAUI) OBLINGER, OF INDEPENDENCE, MISSOURI, ASSIGNOR,

OF ONE-HALF TO ALBERT H. C. BEA'ITY, 0F INDEPENDENCE, MISSOURI.

To all whom it may concern:

Be it known that I, BARRETT G. OBLiNGnR, a citizen of the United States,residing at Independence, in the county of Jackson and State ofMissouri, have invented a new and useful Smoke-Consuming Device, ofwhich the following is a specification.

This invention relates to smoke consuming devices for locomotives. v

The object of the invention is to'provide a novel attachment forlocomotive or other boilers by which the escape of smoke willpractically be overcome, and the loss of heat largely prevented, therebyeffecting a pronounced saving of fuel, and in which the highly heatedproducts will be evenly fed to all the tubes, whereby the rapiddeterioration of those nearest the center of the boiler will beobviated.

As is well known, the tubes of a locomotive boiler nearest its axis arethe first to burn out, thisbeing due to the fact that they are subjectedto the greatest degree of heat. This latter is caused by the dispositionof the tip of the nozzle of the blower which is generally adjusted tocause it to exert its greatest suction on those tubes disposed nearestthe center of the boiler. Various attempts have been made to obviatethis serious defect among which may be mentioned the employment ofperforated plates arranged in front of the tube sheets, but so far as isknown these plates have always been dished or bowed toward the tubesheets, thus producing a result that would be the reverse of thatsecured by the present invention.

WVith the above and other objects in view as will appear as the natureof the invention is better understood, the same consists, generallystated, in the combination with the fire box and tubes of a locomotive,of a perforated deflector secured to the fire box and spaced and dishedaway from the tube sheet, whereby to cause the highly heated gases to bedeflected and thus more evenly distributed to the tubes, therebyprotecting those nearest the axis of the boiler from rapid.deterioration and securing, by the slight retardation of the escape ofthe gases, a more complete combustion, air supply pipes discharging intothe space between the tube sheet and the deflector, and means within thecab of the locomotive to control the passage of air through the pipes.

The invention consists further in the various novel details ofconstruction of a combined smoke consumer and gas deflector forlocomotive boilers, as will be hereinafter more fully described andclaimed.

In the accompanying drawings forming a part of this specification, andin which like characters of reference indicate corresponding parts:Figure 1 is a vertical longitudinal section of so much of a locomotiveas is necessary to a complete understanding of my 1nvention. Fig. 2 is aview partly in elevation and partly in transverse section showing thedeflector more completely.

The locomotive boiler 1 is of the usual or any preferred constructionand provided with the ordinary boiler tubes or flues 2 leading from thefire box 3, in the bottom of which are the usual grate bars 4. Withinthe fire box, I provide a deflector 5 consisting of a circular plate ofmetal having a number of perforations 6 extending through the same and.provided with an annular flange 7 by means of which it may be securedto the front wall of the fire box over the ends of the boiler tubes,hooks 8 having threaded shanks being employed for this purpose, althoughany other form of fastening which will securely hold the deflector andpermit its ready removal for the pur pose of cleaning may be used.

It will be noted by reference to Fig. 1 that the deflector is bowed ordished away from the tube sheet, and this arrangement will cause thegases to be deflected and thus retarded in their escape, so that insteadof the bulk of them passing through those perforations nearest thecenter of the deflector, they will be evenly distributed thereover, sothat all of the tubes will receive practically the same number of heatunits, the result being that the water in the boiler will be morequickly heated, and the conservation of the boiler tubes will besecured.

Extending downward from the lower side of the deflector through the firebox and opening into the air below the, ash pit is a pipe 9, the lowerend of which is covered by a door lO pivoted at one side of the pipe andhaving its edge, at a point diametrically opposite the pivot, engaged bythe end of a connecting rod 11 which is mounted in suitable guides 12 onthe under side of the fire box so that the door may be swung to cover oruncover the lower end of the air pipe by moving the rod forward orbackward. The rear end of the connecting rod 11 is pivoted to the lowerend of a lever 13 which is fulcrumed within the cab of the 10- comotiveand has its upper end formed into a suitable operating handle 14. Asecond air pipe 15 extends along within the upper portion of the firebox and has its front end terminating between the deflector 5 and theboiler flues 2. The other end of this air-pipe 15 extends into the caband is covered by a door 16 pivotally mounted at 17, and provided with ahandle 18 by means of which it may be swung to one side so as to uncoverthe pipe, as will be readily understood.

The operation of the device will be readily appreciated. When a fire iskindled within the fire box the gases and products of combustion risingtherefrom will pass through the deflector 5 to the boiler tubes, thedeflector serving to retard the currents and deflect them, so that thegases and other elements rising from the fire will be confined withinthe fire box for an appreciable period, and, consequently, will beraised to a very high temperature, and further will be distributedevenly to the tubes, thereby preventing their unequal deterioration. Theheated products passing through the deflector 5 will be commingled withthe air fed into the mixing space behind the latter through the pipes 9and 15, and as a result of such commingling will be consumed so that theemission from the smoke stack will be in the form of a light thin vapor.The fiow of air into or through the mixing space between the deflectorand the boiler tubes may be controlled and entirely out off by shiftingthe doors 10 and 16, as will be readily understood.

The device is extremely simple in its construction, may be readilyapplied to any locomotive now in use, and may be quickly removed for thepurpose of repairs or cleaning.

I claim The combination with the fire box and tubes of a locomotive, ofa perforated deflector secured to the fire box and spaced and dishedaway from the tube sheet, whereby to cause the highly heated gases to bedeflected and thus more evenly distributed to the tubes, therebyprotecting thosenearest the axis of the boiler from rapid deteriorationand securing, by the slight retardation of the escape of the gases, amore complete combustion, air supply pipes discharging into the spacebetween the tube sheet and the deflector, and means within the cab ofthe locomotive to control the passage of air through the pipes.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.
